Bug hunting is an art, and you need to be a master. Get Find the Bug, and you'll become one. Long-time Microsoft programmer Adam Barr presents 50 programs, each with exactly one bug. Your assignment: find it. As you do, Barr will teach you how to "think like your processor"... anticipating exactly how code will behave, even without running it. You'll learn better ways to read code, understand it -- and above all, improve it. Whether you're building new systems or maintaining someone else's, you'll find bugs earlier, faster, with less frustration... and write cleaner code to begin with.

Virtualization creates new and difficult challenges for forensic investigations. Operating systems and applications running in virtualized environments often leave few traces, yielding little evidence with which to conduct an investigation. Virtualization and Forensics offers an in-depth view into the world of virtualized environments and the implications they have on forensic investigations. Part I explains the process of virtualization and the different types of virtualized environments. Part II details how virtualization interacts with the basic forensic process, describing the methods used to find virtualization artifacts in dead and live environments as well as identifying the virtual activities that affect the examination process. Part III address advanced virtualization issues, such as the challenges of virtualized environments, cloud computing, and the future of virtualization. After reading this book, you'll be equipped to conduct investigations in these environments with confidence.

This book developed out of the twentieth anniversary conference of the Group for the Study of Irish Historic Settlement held in Dublin in 1989, at which it was decided that the papers should also be published. I would like to thank all the contributors for both their perseverance and their patience which has meant that this book has finally come to see the light of day. I would like to thank especially Dr Ruth Johnson, Curator of DVBLINIA, without whom this book would not have been produced. She spent many hours editing the contributions and she also produced the very successful bibliography which you will find at the end of the volume. Professor Anngret Simms was also very helpful both in reading the draft copy of the book and in the whole editing process. I would also like to thank the library staff in the Royal Irish Academy and Trinity College Dublin, for alltheir assistance. The staff of Routledge, Taylor and Francis Books Ltd are also owed a debt of de ep gratitude by the editor and authors for their efficiency and support in ensuring that this book saw the light of day: especially Victoria Peters, the Archaeology Editor, her Assistant Editor, Nadia Jacobson; and Barbara Duke, Senior Production Editor. Finally, I must also thank the external copy editor, Sophie Richmond, for all her extremely useful observations and corrections. Financialsupport has come from the Department of Medieval History, Trinity College Dublin, the Group for the S tudy of Irish Historic Settlement the Institute of Irish Studies, Queen’s University, Belfast and from the School of Irish Studies, Dublin, for which I am very grateful.
